Describes concrete vibrating equipment and practices in France up to the year 1933 and states that, in general, equipment is similar to the equipment in this country with one exception, viz., "floating pre-vibrators." This piece of equipment is described, Internal vibration is greatly favored over vibration of forms but where the former is impracticable, vibrating of forms is practiced although the economy of compacting by vibration in lieu of hand-tamping was not as marked in France as in this country because of the lower wage scale.
